Knowledge Based Assessment of the Condition of Gas Turbines

The Need

� Gas turbines are the critical drivers of the plant.

� Do not want to stop.

� Need maximum operating efficiency.

� Need to know what to maintain and when.

� Impossible to manually assess the turbine condition.

The Desire

� Understand the condition of the turbine.

� Detect problems at the earliest possible stage.

� Understand what happens when problems arise.
